HeatingUsing the system
The heating system delivers air into the interior of the vehicle and
warms it as required.Fig. 106 Heating: Control elementsSetting temperature– Turn the control dial fig. 106 to the right in order to increase the temperature.
– Turn the control dial to the left in order to increase the temperature.Controlling blower– Turn the blower switch into one of the po sitions, 1 to 4, in order to switch the
blower on.
– Turn the blower switch into position 0 in order to switch the blower off.
– If you wish to shut off the fresh air supply , use the button - recirculated air mode
 .Control for air distribution– You can adjust the direction of the air flow using the air distribution control
 page 94.
Rear window heater– Press button . Further information page 59, “Rear window heater”.Auxiliary heating (auxiliary heating)*– Press the button in order to directly switch on/off the auxiliary heating (auxiliary
heating and ventilation). Further information page 104, “Auxiliary heating (auxil-
iary heating and ventilation)*”.
The air inlet in front of the windscreen must be free of ice, snow or leaves in order to
ensure that the heating and ventilation systems operate properly.
The heating effect is dependent upon the c oolant temperature, thus full heat output
only occurs when the engine has reached its operating temperature.
The blower should aways be on to prevent the windows from misting up.
WARNING
You should not leave recirculated air mode on over a longer period of time, as
“stale” air may result in fatigue in the driver and occupants, divert your atten-
tion and also cause the windows to mist up. The risk of having an accident
increases. Switch recirculated air mo de off as soon as the windows begin
misting up.

Recirculated air mode
In recirculated air mode air is sucked out of the interior of the vehicle
and then fed back into the interior.Recirculated air mode prevents polluted air outside the vehicle from getting into the
vehicle, for example when driving through a tunnel or when standi ng in a traffic jam.Switching recirculated air mode on– Press the button - the warning light lights up in the button page 95, fig. 106 .Switching recirculated air mode off– Press again the button - the warning light in the button goes out.
The recirculated air mode is switched off automatically if the air distribution control
is in position
  page 95, fig. 106. You can also switch recirculated air mode on
again from this setting by repeatedly pressing button .
WARNING
You should not leave recirculated air mode on over a longer period of time, as
“stale” air may result in fatigue in the driver and occupants, divert your atten-
tion and also cause the windows to mist up. The risk of having an accident
increases. Switch recirculated air mode off as soon as the windows begin
misting up.Climatic* (semi-automatic air conditioning system)Description
The Climatic is a combined coolin g and heating system. It makes it
possible to optimally control the air temperature at any season of the
year.Description of the Climatic
It is important for your safety and for your driving comfort that the Climatic is operating
properly. The cooling only operates if button
page 98, fig. 107 is pressed, and the
following conditions are met:

engine running,

outside temperature above approx. +2°C and

blower switch switched on (positions 1 to 4).
If the cooling system is switched on, the temperature and air humidity drops in the
vehicle. The wellbeing of the occupants of the car is enhanced as a result of this partic-
ularly at high outside temperatures and a high air humidity. The system prevents the
windows misting up during the cold season of the year.
The heating effect is dependent upon the c oolant temperature, thus full heat output
only occurs when the engine has reached its operating temperature.
It is possible to briefly activate recirculat ed air mode in order to enhance the cooling
effect  .
Air at a temperature of about 5°C may flow out of the vents under certain circum-
stances when the cooling system is operating. Lengthy and uneven distribution of the
air flow out of the vents and large differences in temperature, for example when getting
out of the vehicle, can result in chills in sensitive persons.
The air inlet in front of the windscreen must be free of ice, snow or leaves in order to
ensure that the heating and cooling systems operate properly.
After switching on the cooling Condensation from the evaporator of the air condi-
tioning may drip down and form a puddle be low the vehicle. This is quite normal and
not an indication of a leak!
WARNING

For your own safety and that of other road users, ensure that all the
windows are free of ice, snow and misting. Please familiarize yourself about
how to correctly operate the heating and ventilation systems, how to demist
and defrost the windows, as well as with the cooling mode.

You should not leave recirculated air mode on over a longer period of time,
as “stale” air may result in fatigue in the driver and occupants, divert your
attention and also cause the windows to mist up. The risk of having an accident
increases. Switch recirculated air mo de off as soon as the windows begin
misting up.

“stale” air may result in fatigue in the driver and occupants, divert your atten-
tion and also cause the windows to mist up. The risk of having an accident
increases. Switch recirculated air mode off as soon as the windows begin
misting up.Using the air conditioning system economicallyThe compressor on the air conditioning syst em uses power from the engine when in
cooling mode which will effect the fuel consumption.
It recommended to open the windows or the doors of a vehicle for which the interior
has been strongly heated through the effect of direct sunlight in order to allow the
heated air to escape.
The cooling system should not be switched on while travelling when the window is
open. The desired interior temperature can also be achieved without switching in the cooling
system just by switching to fresh air mode.
For the sake of the environment
When you economize on fuel, you
also reduce pollutant emissions.Operational malfunctionsIf the cooling system does not operate at outside temperatures higher than +5 °C,
there is a problem in the system. The reasons for this may be:
The fuse on the air conditioning system has blown. Check the fuse, replace it if
necessary page 226.

The cooling system has switched off auto matically for a short time because the
coolant temperature of the engine is too hot  page 16.
If you are not able to rectify the operational problem yourself, or if the cooling capacity
decreases, switch the cooling system off. Contact a specialist garage.
Climatronic* (automatic air conditioning)Description
The Climatronic system is a combinat ion of an automatic heating, fresh
air and cooling system which provides optimal comfort for the occu-
pants of the car.The Climatronic maintains fully automatically a convenience temperature. This is
achieved by automatically varying the temperature of the outflowing air, the blower
stages and the air distribution. The system also takes into account sunlight which elim-
inates the need to alter the settings manually. The automatic mode  page 102
ensures maximum wellbeing of the occupants at all times of the year.

The AC compressor is switched off at a hi gh coolant temperature in order to provide
cooling at a high load of the engine.
After switching on the cooling Condensation from the evaporator of the air condi-
tioning may drip down and form a puddle be low the vehicle. This is quite normal and
not an indication of a leak!
Recommended setting for all periods of the year:

Set the desired temperature, we recommend 22°C.

Press the button page 102, fig. 108 .

Move the air outlet vents 3 and 4 so that the air flow is directed slightly upwards.
WARNING

For your own safety and that of other road users, ensure that all the
windows are free of ice, snow and mistin g. Please familiarize yourself about
how to correctly operate th e heating and ventilation systems, how to demist
and defrost the windows, as well as with the cooling mode.


as “stale” air may result in fatigue in the driver and occupants, divert your
attention and also cause the windows to mist up. The risk of having an accident
increases. Switch recirculated air mode off as soon as the windows begin
misting up.
Note

If the cooling system has not been switched on for a lengthy period, odours may
be produced at the evaporator because of deposits. Switch the cooling system on at
least once a month for approximately 5 minu tes at the highest blower stage - also
during the cold season of the year - in order to avoid such odours. Also open a window
for a short time.

We recommend that you do not smoke in the vehicle when the recirculating air
mode is operating since the smoke which is drawn at the evaporator from the interior
of the vehicle forms deposits in the evapor ator of the air conditioning system. This
produces a permanent odour when the air conditioning system is operating which can
only be eliminated through considerable effort and expense (replacement of
compressor).

The used air streams out through the air removal openings in the luggage compart-
ment.

On vehicles equipped with a factory-fitted radio* or navigation*, the information
of the Climatronic is also shown on the display. This function can be switched off, see
operating instructions of the radio* or the navigation system*.

Note

If the windscreen mists up, press the button page 102, fig. 108 . After
the windscreen has been demisted, press the button .

The automatic air distribution control oper ates only if the outside temperature is
higher than approx. 2°C.
Controlling blower
There are a total of seven blower stages available.The Climatronic system controls the blower stages automatically in line with the inte-
rior temperature. You can also , however, a dapt the bl ower stages ma nua lly to suit y our
particular needs.
– Press again the button on the left side (reduce blower speed) or on the right side (increase blower speed).
If you switch off the blower, th e Climatronic is switched off.
The set blower speed is displayed above the button when the respective number
of warning lights come on.
WARNING

“Stale air” may result in fatigue in the driver and occupants, reduce atten-
tion levels and also cause the windows to mist up. The risk of having an accident
increases.

Do not switch the Climatronic system off for longer than necessary.

Switch the Climatronic system on as soon as the windows mist up.
Defrosting windscreenDefrosting windscreen - switching on– Press the button page 102, fig. 108 .Defrosting windscreen - switching off– Once again press the button or the button .
The temperature control is controlled automatically. More air flows out of the air outlet
vents 1.Auxiliary heating (auxiliary heating and ventilation)*Description and important information
The auxiliary heating (auxiliary he ating and ventilation) heats or
supplies the interior of the vehicl e with fresh air independent of the
engine.Auxiliary heating (auxiliary heating)
The auxiliary heating (auxiliary heating) functions in connection with the Climatic or
Climatronic.
It can be used when stationary, when engi ne is switched off for preheating of the
vehicle as well as while driving (only during the heating phase of the engine).
The auxiliary heating (auxiliary heating) wa rms up the coolant during the combustion
of fuel from the vehicle tank. The coolant warms up the air, which (if the blower speed
is not set to zero) flows into the occupant compartment.
Auxiliary ventilation
The auxiliary ventilation enables fresh air to flow into the vehicle interior by switching
off the engine, whereby the interior temperature is effectively decreased (e.g. with the
vehicle parked in the sun).

WARNING

The auxiliary heating must never be operated in closed rooms - risk of
poisoning!

The auxiliary heating must not be runn ing during refueling - risk of fire.

The exhaust pipe of the auxiliary heating is located on the underside of the
vehicle. Therefore do not place the vehicl e, if you wish to operate the auxiliary
heating, in such a way that the exhaust gases of the auxiliary heating can come
easily into contact with inflammable mate rials (e.g. dry grass) or easily inflam-
mable substances (e.g. fuel run out).Note

If the auxiliary heating runs, the fuel consumption comes from the vehicle tank.
Therefore the auxiliary heating should not be op erated, if there is very little fuel in the
tank.

The exhaust pipe of the auxiliary heating, which is located on the underside of the
vehicle, must not be clogged and the exhaust flow must not be blocked.

If the auxiliary heating and ventilation is running, the vehicle battery discharges. If
the auxiliary heating and ventilation has be en operated several times over a longer
period, the vehicle must be driven a few ki lometers in order to recharge the vehicle
battery.

The auxiliary heating only switches the blower on, if it has achieved a coolant
temperature of approx. 50 °C.

At low outside temperatures, this can result in a formation of water vapour in the
area of the engine compartment. This is quite normal and is not an operating problem.

After switching off the auxiliary heating, the coolant pump runs for a short period.

The auxiliary heating and ventilation does not switch on or comes on, if the vehicle
battery indicates a low loading state.

The auxiliary heating (auxiliary heating) does not switch on, if the following was
shown in the information display or before switching off the ignition: Please refuel!
(Please refuel!) .

The air inlet in front of the windscreen must be free of ice, snow or leaves in order
to ensure that the auxiliary heating operates properly.

So that warm air can flow into the vehicl e interior after switching on the auxiliary
heating, you must maintain the temperature normally selected by you (we recom-
mend 22°C). It is recommended to put the air flow in the position
.

On vehicles with DPF (diesel particle filter) the warm coolant heats up the engine.
Direct switching on/offThe auxiliary heating (auxiliary heating and vent ilation) can be switched on or off at any
time directly using the button on the operating part of the Climatic fig. 109 or
on the operating part of the Climatronic.
If the auxiliary heating and ventilation is not switched off earlier, it switches off auto-
matically after the expiration of the set operating period, in the menu Running time.Using the system
So that the auxiliary heating (auxiliary heating and ventilation) func-
tions according to your expectations, it is necessary to carry out the
basic setting before its programming.Basic setting– On the information display, select from the Main menu the menu point

– Pull the lever below the steering wheel down fig. 110 - left  .
– Set the steering wheel to the desired position (concerning height and forward/back position).
– Push the lever upwards as far as the stop.
WARNING

You must not adjust the steering wheel when the vehicle is moving!

The driver must maintain a distance of at least 25 cm to the steering wheel
 fig. 110 - right. Not maintaining this minimum distance will mean that the
airbag system will not be able to properly protect you - hazard!

For safety reasons the lever must always be firmly pushed up to avoid the
steering wheel altering its po sition unintentionally when driving - risk of acci-
dent!

If you adjust the steering wheel furthe r towards the head, you will reduce
the protection offered by the driver airbag in the event of an accident. Check
that the steering wheel is aligned to the chest.

When driving, hold the steering wheel with both hands firmly on the outer
edge in the 9 o'clock and 3 o'clock po sition. Never hold the steering wheel
firmly in the 12 o'clock position or in another way (e.g. in the middle of the

You should not switch on any major elec trical components during the heating
period otherwise the vehicle battery will be drained unnecessarily.
- start engine
Applies to all models:
Position
To lock the steering , with the ignition key withdrawn, turn the steering wheel until the
steering locking pin is heard to engage. You should always lock the steering as a general
rule if you leave your vehicle. This acts as a deterrent against possible theft of your
vehicle .
Position
Move the steering wheel back and forward a little if the ignition key cannot, or cannot
easily be turned into this position, in order to release the steering lock.
Position
The engine is started in this position. At th e same time switched on low beam or main
beam or other electrical components wi th major power consumption are briefly
switched off. The ignition key moves back into position when one releases the key.
The ignition key must be turned back into position each time before starting the
engine again. The starter repeat lock in th e ignition lock prevents the starter being
engaged when the engine is r unning and thus getting damaged.
Ignition key withdrawal lock (automatic gearbox)
You can only withdraw the ignition key after switching off the ignition if the selector
lever is in position P.
WARNING

When driving, the ignition key must always be in the position (ignition
switched on) without the engine running. This position is indicated by the
warning lights coming on. If this is not the case, it could result in unexpected
locking of the steering wh eel - risk of accident!

Only remove the ignition key from the ignition lock when the vehicle has
come to a standstill (by applying the handbrake or moving the selector lever
into the position P). The steering lock can engage imme diately - risk of acci-
dent!

Always withdraw the ignition key if you are going to leave the vehicle, even
for a short time. This is particularly important if children are left in the vehicle.
The children might otherwise start the engi ne or switch on electrical equipment
(e.g. power windows) - risk of accident or injury!
Starting the engineGeneral
You can only start the engine only using an original ignition key.
Place the gearshift lever into neutral (or place the selector lever to the position P or
N in the case of an automatic gearbox) and put on the handbrake firmly before starting
the engine.

Before starting, it is necessary to depres s the clutch pedal and to hold it pressed
until the engine starts. If you start the engi ne without depressing the clutch pedal, the
engine does not start and a message is shown in the display of the instrument cluster
to remind you of th e necessity to depress the clutch pedal.

Let go of the key as soon as the engine starts otherwise there may be damage to
the starter.
The engine running noises may louder at first be louder for a short time after starting
the cold engine until oil pressure can be built up in the hydraulic valve clearance
compensation. This is quite normal and is not an operating problem.
If the engine does not start ...
You can use the battery of anothe r vehicle as a jump-start aid page 221.
It is only possible to tow-start vehicles fi tted with a manual gearbox. The tow-starting
distance must not be more than 50 metres page 225.
